巴西采购需求：Tc 药品供应商、Tc 药品批发、Tc 药品分销、Tc 药品采购、Tc 药品进口商、Tc 药品制造商

I'm interested in obtaining detailed pricing information for a variety of herbal products that your factory offers. Specifically, I would like to know the price ranges for bulk orders, as well as any available discounts for larger quantities. Additionally, please include information on minimum order quantities and lead times for production and delivery. It would also be helpful if you could provide any relevant specifications or grades of the herbal products, along with any certifications or quality assurance processes in place. Understanding your packaging options and any potential customization would be beneficial as well. Looking forward to your prompt response with the requested details!
